we found that using OpenSearch High REST Client doesn’t work with Elasticsearch anymore.
We are using 1.3.2 version with Elasticsearch 7.10 and OpenDistro and it works just fine. Now we upgraded to OpenSearch 2.x and that API fails in many cases. Upgrading to v2 of that API brakes the functionality with Elasticsearch 7.10. Is it expected? There was an announcement made a while ago that the API will work with both ES and OpenSearch?
Thanks in advance for any help.
